In Sweden January 19, 1935 I Claims.

This invention relates to tip-wagons and has for its object to provide a simple and reliable construction whereby the body of the wagon easily can be tipped to either side and rearwards at will directly by hand or by simple means. The invention is applicable not only to carts and the like but also to motor and railway wagons.

A preferred embodiment of the invention is illustrated in the accompanying drawings in which:-

Fig. l is a plan View of a tip-wagon constructed in accordance with the invention. Fig. 2 is a sectional side view of the wagon. Fig. 3 is a vertical cross section substantially on the line III-III in Fig. 2. Fig. 4 is a detail section on a. larger scale. Fig. 5 is a sectional side view of the wagon and illustrates a modification.

Referring to the drawings, l represents the undercarriage of the vehicle, and 2 the body thereof, which can be tipped at either side and rearwards. Secured to the undercarriage there are two longitudinal section irons 3 and 4 and a transverse section iron 5 located behind the rear ends of the longitudinal irons 3 and 4. The said section irons 3, 4 and 5 all may consist of angle irons as shown, and they all have vertical webs having free upper edges. Preferably all the said angle irons 3, 4 and 5 are riveted or otherwise secured to a base plate 6 which in turn is screwed or fastened in any other suitable manner to the undercarriage l of the vehicle.

Secured to the under side of the body 2 there are two longitudinal section irons 1 and 8 and a transverse section iron 9 each having a depending vertical web, the depending webs of the two longitudinal irons I and 8 being located just inside of the respective vertical webs of the irons 3 and.

4, and the depending web of the transverse iron 9 being located just in front of the vertical web of the iron 5. Preferably also the section irons I, 8 and 9 are in the form of angle irons, and preferably they are riveted or otherwise secured to a base plate In which in turn is screwed or fastened in any other suitable manner to the under side of the body 2. Outside of the depending web of each of the longitudinal irons l and 8' and rearwardly of the depending web of the transverse iron 9' there are secured section irons, preferably angle irons II having depending webs forming with the depending web of the respective angle irons 1, 8

- and 9 inverted channels for receiving the vertical webs of the respective angle irons 3, 4 and 5 on the undercarriage l. Preferably the depending webs of the said angle irons ll art inclined as shown.

As will be seen from the drawings the body 2 of the wagon rests on the upper free edges of the vertical webs of the section irons 3, 4 and 5, which webs are received Y in the inverted channels of wedge-shaped cross section, which are composed 5 of the depending vertical webs of the angle irons 1, 8 and 9 and the inclined depending webs of the angle irons H. Thus the body 2 has no rigid or permanent connection-with the undercarriage of the vehicle and, therefore, is easily removable. 10 For locking the body 2 to the undercarriage of the vehicle there is provided at each side and at the rear a releasable locking bolt !2 passing through holes in the depending webs on the irons forming the inverted channel and through a hole I3 '15 in the vertical web received in the channel, as'is most clearly shown in Fig. 4. The hole I3 is larger than the diameter of the locking bolt I2 and may have the form of a slot. The locking bolts [2 may be slidably mounted in brackets M on the body! 20 and actuated by springs l5 which tend to move and hold the locking bolts in looking position. Preferably the locking bolts are so arranged that they can be locked in retracted (released) position, for instance by slightly rotating the bolts after they have been retracted. Pivoted in a bracket It at the center of the plate In on the under side thereof there is a short supporting .arm H. In the modification shown in Fig. 5 this arm ll is'provided with a longitudinal slot, one edge of which is in the form of a rack l8 engaging a pinion it which is connected by means of a worm gear or the like to a crank shaft 20 ,or the like by means of which the pinion l9 can be rotated. the said worm gear or the like being housed p35 in a housing 2! rigidly secured to the undercarriage of the vehicle. a

When it is desired to tilt the body 2 rearwards the locking bolts 12 at the sides of the wagon I are released, whereas the locking bolt I2 at the 40 rear is left in locked position. Then the body can be tilted rearwards directly by hand by lifting the front end of the body (the embodiment of the invention shown in Figs. 1-3), or by rotating the pinion l9 by operating the crank shaft 20 to raise the arm H as shown in Fig. 5. In the embodiment shown in Figs. 1-3 the arm l1, when the body 2 is tilted, by its own weight turns on its pivot and takes a substantially vertical position in which it will then support the body 2 .5 in the tilted position. When the body 2 is to be tilted back in normal position the arm l l sim- E ply is swung away so that it no longer forms a support for the body 2. It will be seen that .the body 2, when it is titlted rearwards, turns on the 55 upper edge of the vertical web of the angle iron 5. When the body 2 is to be tilted to one side, the locking bolts l2 at the other side and at the rear are released, and tilting is effected just in the same simple manner as just described, the body 2 in this instance turning on the upper edge of the vertical web of the respective side iron 3 or 4.

Of course I do not limit myself to the precise construction herein shown for the purpose of illustration only, since the construction can be varied and modified in several respects within the limits of the invention. For instance the inverted channels on the under side of the body 2 for receiving the upwardly projecting webs or flanges of the section irons on the undercarriage of the Vehicle may consist of channel irons in-' stead of being composed of angle iron as herein shown.

What I claim and desire to secure by Letters Patent is:--
